ROLAND MARTIN

Research Scientist in Geophysics

Department of Modeling and Imaging in Geosciences, University of Pau, France

My name is Roland Martin, I am a Senior Research Scientist in the Department of Modeling and Imaging in Geosciences at University of Pau, France.

My research interests include the numerical study of wave propagation in geological structures, multiphase flow imaging, . I use a variational formulation of the equations of elastodynamics, and solve it using the so-called spectral-element method, a high-order version of the finite-element method, which can be shown to be very accurate at low cost, and particularly well suited to an efficient implementation on parallel computers. This work is done in collaboration with Prof. Dimitri Komatitsch (University of PAU). We apply such numerical techniques to the study of wave propagation in complex media for oil industry purposes. An effort is done also in the implementaion of optimized boundary conditions (PML) for elastic wave propagation, electromagnetics, shallow water and Navier Stokes equations.

I am working with Alejandro Rodriguez Castellanos (Instituto Mexicano del Petroleo/IMP-Mexico) and Francisco Sanchez Sesma (Universidad Nacional Autonoma de Mexico/UNAM-Mexico) on wave propagation in fractured media using Indirect Boundary Element methods. I am collaborating in Reconstruction and Imaging algorithms with Carlos Ortiz-Alemàn and Carlos Gamio Roffé of IMP using iterative (Projected Landweber) or stochastic (Simulated annealing, genetic algorithms) for multiphase flow measurement in fluidized beds or oil-gas-solids mixtures.

Recently I started a collaboration with Prof. Roberto Zenit of the Complex Materials Department of UNAM for the numerical simulation of vortex impacts on plates and the study of heat transfers.

Main interests:

- Numerical Wave propagation using Spectral element methods, Finite Difference and Integral Boundary Element methods

- Perfectly Matched Layers (PML) for elastic wave equations, shallow water equations, Navier Stokes equations.

- Capacitance Tomography using simulated annealing and genetic algorithms.

- Fluid Mechanics: Study of heat transfer due to Impacts of jets on plates.

With some colleagues, we have started an INRIA project called MAGIQUE-3D.

I also work with Carlos-Ortiz Aleman and Carlos Gamio Roffé from Instituto Mexicano del Petroleo, Mexico City, France, on reconstruction algorithms for multiphase flow measurement. Iterative processes like Gauss-Newton methods or stochastic techniques like Simulated annealing and Genetic algorithms provide successful dynamic 2D and 3D reconstructions. Further improvements are being performed in order to reduce computational costs in running time and memory storage.

Before working in Pau, I was a Senior Research Fellow in the Programa de Computacion y Matematicas Aplicadas at Instituto Mexicano del Petroleo in Mexico City.
